\ JAMES W. SMALLMAN, OF NUNEATON, ENGLAND.

HAU LAG E-CLI P.

SPECIFICATION forming part'jof. Letters Patent No. 728,421, dated May 19, 1903.

Application filed September 12, 1902. Serial Il'o. 123,176. (No model.)

To all whom it may concern.-

Be it known that I, JAMES W. SMALLMAN, a subject of the King of Great Britain and Ireland, residing at Nuneaton, in the county .of Warwick, England, have invented certain new and useful Improvements in Haulage- Clips, of which the following is a specification.

This invention relates to clipsprincipally employed in connecting tubs or wagons to endless-wire ropes for mineral haulage.

The accompanying drawings will now be described.

Figure 1 is an elevation showing the righthand side of the clip, the coupling-hook and the rope being indicated by dotted lines. Fig. 2 is a vertical section on the line a; no in Fig. 1 looking in the direction of the arrowwith the hook and the coupling-pin omitted. Fig. 3 is a plan, on a larger scale,'i llustrating thesquare-headed bolt with its separate bearing collar, the bearing-nut being in section. Fig. 4 is an end elevation of the bearing-nut. Fig. 5 represents a bolt having a special head and provided with the bearing-collar and an ordinary hexagonal nut.

The bolt A has a square head a. The bearing-collar B is formed with horizontal rounded edges 1) and b and fits easily on the neck of the bolt A. The bearing-nut C, f0rmed with horizontal rounded edges 0 andc', isan easy fit for the threaded part of the bolt A. The bolt A, the bearing.- collar B, and the bearing-nut O loosely connect the two shells R and L. These shells are causedto grip or permitted to release the rope by the lever D,

which is furnished with a trunnion-peg 01, working in a hole in the upper part of the shell R and in a correspondinghole in the. upper part of the shell L. The shells ;R and L in rocking on the bearing-collar B andbearing-nut O can exert no pressureabove or below the bolt A, and consequentlylt-hat bolt is not subjected to a bending strain,- nor'can the shell L bruise the thread and so prevent the turning of the said bolt with the fingers that it will remain in either of two positions. In one position (into which it is turned by hand) it lies away from the projections on the shells and permits the handle of the lever to be raised; but in the other or working position (into which it falls automatically while the handle of the lever is being depressed) it rests against the shells beneath the said projections and locks the lever. The spiral spring Gr,which encircles the bolt A, maintains the shells R and L in their extreme positions, thus facilitating the attachment of the clip to the rope, and after the clip is detached that spring by keeping the adjustable members underpressure guards against the accidental alteration of the adjustment. The coupling (which may be of any suitable kind) is conresponds in form and size with the bearingnut O, which is dispensed with, the rounded edges j and j taking the places of the rounded edges 0 and c. The threaded part of the bolt goes through the bearing-collar B (which protects the thread required for adjustment) and extends far enough to receive an ordinary hexagonal nut K, whereby adjustment is effected.

- What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a haulage-clip, the combination, with two shells, and a lever working between them, of a bolt that connects the shells, and horizontal bearing edges carried by the bolt, substantially as set forth.

2. In a haulage-clip, the combination, with two shells, and a lever working between them,

of a bolt that connects the shells, horizontal bearing edges carried bythe bolt, and means for adjusting the distance between the horion the bolt for maintaining the shells in their 1 6. In a haulage-clip, the combination, with extreme positions, substantially as set forth. two shells, a lever Working between them, and 5. In a haulage-clip, the combination, with a safety-catch mounted upon and serving to twosl1ells,andalever workingbetween them, look the lever, of a belt that connects the 5 of a belt that connects the shells, horizontal shells, and horizontal bearing edges carried 15 bearing edges carried by the bolt, means for by the bolt, substantially as set forth. adjusting the distance between the horizontal JAMES W. SMALLMAN. bearing edges, and a spring on the bolt for maintaining the shells in their extreme posi- 1o tions, substantially as set forth.
